Introduction
The 753 and 754 Documenting Process Calibrators (the
Product) are battery-powered, hand-held instruments that
measure and source electrical and physical parameters. In
addition, the 754 supplies basic HART communicator
functions when used with HART-capable transmitters. See
the 754 HART Mode Users Guide for instructions on how to
use the HART communication feature.
The Product helps troubleshoot, calibrate, verify, and
document work performed on process instruments.
Note
All figures in this manual show the 754.

• Connect the common test lead before the
live test lead and remove the live test lead
before the common test lead.
• Use only current probes, test leads, and
adapters supplied with the Product.
• Do not touch the probes to a voltage
source when the test leads are connected
to the current terminals.
• Use only cables with correct voltage
ratings.
• Do not use test leads if they are damaged.
Examine the test leads for damaged
insulation, exposed metal, or if the wear
indicator shows. Check test lead
continuity.
• Examine the case before you use the
Product. Look for cracks or missing
plastic. Carefully look at the insulation
around the terminals.
• Always put the stackable end of the test
lead into a terminal of the Product.

Display
Figure 6 and Table 5 show a typical display. The display
shown is MEASURE mode. Near the top of the display is
“Source Off.” This display area shows what is happening in
the other mode (SOURCE or MEASURE). The other parts
of the display are:
• Status Bar: Shows the time and date, and the status of
Loop Power, Auto Battery Save, and Backlight Timeout;
all of which are set in Setup mode. The selected HART
channel (if HART is active-754 only) and low-battery
and backlight-on symbols are also show here.
• Mode Indicator: Shows if the Product is in MEASURE
or SOURCE mode. In split screen
MEASURE/SOURCE mode, there is a Mode Indicator
for each window.
• Measured Value: Shows the measured value in a
selection of engineering units or percent of scale.
• Range Status: Shows if Auto Range is on, and what
range is currently in operation.
• Custom Units Indicator: Shows that the displayed
units are custom. The initial engineering units of the
measure or source function are not shown.

The Battery
Caution
For safe operation and maintenance of the
product:
• Do not keep cells or batteries in a
container where the terminals can be
shorted.
• Repair the Product before use if the battery
leaks.
• Remove battery to prevent battery leakage
and damage to the Product if it is not used
for an extended period.
• Connect the battery charger to the mains
power outlet before the Product.
• Use only Fluke approved power adapters
to charge the battery.
• Keep cells and battery packs clean and
dry. Clean dirty connectors with a dry,
clean cloth.
• Do not short the battery terminals together.
Warning
To prevent personal injury:
• Do not put battery cells and battery packs
near heat or fire. Do not put in sunlight.
• Do not disassemble or crush battery cells
and battery packs.
• Do not disassemble the battery.
• Batteries contain hazardous chemicals that
can cause burns or explode. If exposure to
chemicals occurs, clean with water and get
medical aid.
Charge the Battery
Before you use the Product for the first time, charge its
battery.
To charge the battery while it is inside the Product:
1. Turn the Product OFF.
2. Connect the battery charger to the Product and keep it
OFF. The battery will not charge if the Product is on.
The battery fully charges in 8 hours while inside the Product.
See Figure 8.
To charge the battery while it is outside of the Product:
1. Turn the Product face down.
2. Use a flat-head screwdriver and move the battery lock
from (locked) to (unlocked).

3. Remove the battery.
4. Connect the battery charger to the input. Outside of the
Product, the battery will charge in 5 hours.
Note
An optional 12-Volt car charger is available. See
“Accessories”.
Battery Charge Level
Use these two methods to make sure the Battery is
charged:
• See the Battery Gauge Bar Graph on the display.
• See the Battery Charge Indicator on the battery.
The Battery Charge Indicator can be seen while the battery
is outside of the Product. With the battery removed and not
connected to its charger, push the button below the Battery
Charge Indicator. Solid Green LEDs show the level of
charge on the battery. The Battery is fully charged when all
LEDs are illuminated.
Connect the battery charger to the battery and push the
button below the Battery Charge Indicator. LEDs flash to
show the charge level but also show that the battery is being
recharged. As the battery charges, the LED flashes and
moves to the top of the charge indicator.
Battery Life
The battery gauge bar graph is shown on the upper
right of the display.
Table 6 shows the typical operation time for a new, fully-
charged battery. Product performance is guaranteed to its
specification until the battery gage reads empty ().

Resistance-Temperature Detectors (RTDs)
The Product accepts RTD types shown in Table 8. RTDs are characterized by their resistance at 0 °C (32 °F), which is called
the “ice point” or R0. The most common R0 is 100 Ω. A large number of RTDs come in a three-terminal configuration. The
Product accepts RTD measurement inputs in two-, three-, or four-wire connections. See Figure 17. A four-wire configuration
gives the highest measurement precision, and two-wire gives the lowest measurement precision.

as shown if using a 3-wire connection.
8. Push .
Caution
To prevent possible damage to the Product, do
not force a dual banana plug between any two
jacks in the horizontal orientation. Doing so
will damage the jacks. Use the supplied jumper
wire when needed for RTD measurements. A
dual banana plug may be used in the vertical
orientation. See Figure 16.

Damping Measurements
The Product normally applies a software filter to dampen
measurements in all functions except continuity. The
specifications assume that damping is turned on. The
damping method is a running average of the last eight
measurements. Fluke recommends leaving damping on.
Turning damping off may be useful when measurement
response is more important than accuracy or noise
reduction. To turn damping off, push the More Choices
softkey twice, then push the Dampen softkey so that Off is
shown. Push Dampen again to turn damping back on. The
default state is On.
Note
If a measurement falls outside a random noise window,
a new average is started. If damping is turned off, or
until measurements are fully damped, the symbol is
displayed.
Source Mode
The operating mode (for example, MEASURE, SOURCE) is
shown on the display. If the Product is not in SOURCE
mode, push until SOURCE is shown. The Product
must be in SOURCE mode to change any of the SOURCE
parameters.
Source Electrical Parameters
To select an electrical source function:
1. Connect the test leads as shown in Figure 18,
depending on the source function.
2. Push for current, for dc voltage, h for
frequency, or q for resistance.
3. Record the necessary output value, then push . For
example, to source 5.5 V dc, push 5 . .

Note
If sourcing frequency, respond when the Product
asks you to select a zero-symmetric sine or
positive square wave. The amplitude specified is
p-p amplitude.
4. To change the output value, record a new value and
push .
Note
If sourcing current, wait for the
g
symbol to
disappear before you use the output.
5. To set the output value in the present source function,
push then enter the desired value and push .
6. To turn off sourcing completely, push twice.
Note
Use the source current function to drive a current
loop. This is different than the loop power function
in which the Product is powering a process
instrument. To source loop power, use the Loop
Power function accessible from Setup mode.
